Mfr. No.: APRH100151C

815421021141 With the popularity of short, pistol-length, AR-style firearms on the market, more of today's AR owners are seeing a phenomenon that occurs on semi-automatic firearms with short gas systems: overgassing. The result of overgassing is increased wear on internal components, as well as increased felt recoil. To address these issues, Aero Precision launched its AR-15 Carbine Buffer Kit. Several options are available in the company's Carbine Buffer Kit lineup. Each kit ships with a mil-spec buffer tube machined from 7075-T6 aluminum and features slots for a six-position buttstock. The kits also include a buffer spring, end plate and castle-lock nut. However, where the kits differ is in the weight of the included buffer. The Aero Precision AR-15 Carbine Buffer Kit can be had with a standard buffer spring, a H (Heavy) buffer, an H2 buffer or a heavy H3 buffer, so AR owners can fine-tune their operating system to reduce overgassing. Buffer weights are 3 ounces, 4 ounces, 4.6 ounces or 5.6 ounces, respectively.

A Complete Buffer Kit for Your AR-15 Carbine

With the increasing popularity of short, pistol-length AR-style firearms, many AR owners are experiencing a common issue associated with semi-automatic firearms that have short gas systems: overgassing. This can lead to increased wear on internal components and heightened felt recoil.

Introducing the Aero Precision AR-15 Carbine Buffer Kit

To combat these challenges, Aero Precision has developed the AR-15 Carbine Buffer Kit. This kit is designed to help you optimise your firearm's performance and enhance its longevity.

  • Mil-Spec Buffer Tube: Each kit includes a buffer tube machined from 7075-T6 aluminium, ensuring durability and reliability.
  • Adjustable Buttstock: Features slots for a six-position buttstock, allowing for customisation to fit your shooting style.
  • Complete Kit: The kit comes with a buffer spring, end plate, and castle-lock nut for easy installation.
  • Buffer Weight Options: Choose from a standard buffer spring, H (Heavy) buffer, H2 buffer, or heavy H3 buffer to fine-tune your operating system and reduce overgassing.

The buffer weights available are:

  • Standard Buffer: 3 ounces
  • H Buffer: 4 ounces
  • H2 Buffer: 4.6 ounces
  • H3 Buffer: 5.6 ounces

Upgrade your AR-15 with the Aero Precision Carbine Buffer Kit and experience improved performance and reduced wear on your firearm.
